Abstract: A semiconductor memory device comprises a number of dynamic memory cells, each consisting of a capacitor (C I ) and a field effect-type switching transistor (Q 2 ) arranged at points of intersection of a plurality of bit lines (BL) and word lines (WL). The source or drain electrode of the transistor (0 2 ) is connected tq a reference potential line (RL) and the other of the source or drain electrode is connected to one electrode of the capacitor (C I ). The bit line (BL) is commonly connected to the other electrode of the capacitors of the memory cells arranged along that bit line (BL). The word line (WL) is commonly connected to the gate electrode of the switching transistors (Q 2 ) of the memory cells arranged along that word line (WL). The area of the capacitor (C 1 ) is greater than the area of an electrode portion connecting the transistor (Q 2 ) to the capacitor (C I ). This enables the area of the capacitor (C 1 ) to be maximised whilst reducing the parasitic capacitance of the lines to a minimum.

Abstract: Bei einem Drucker nach der Erfindung besitzt die Trommel zur Aufnahme blattförmiger Unterlagen wenigstens einen sich in Umfangsrichtung erstreckenden Schlitz, in den Klemmelemente einführbar sind, um die Unterlage festzuklemmen. Die Steuerung der Klemmelemente erfolgt mit Hilfe von z.B. an den Stirnflächen der Trommel befestigten Scheiben, in deren Umfang die Klemmelemente ebenfalls eingreifen. Die Scheiben sind dabei an ihrer Außenseite mit einem ersten Stopperelement versehen, das mit einem am Gehäuse der Vorrichtung angeordneten zweiten Stopperelement derart federnd zusammenwirkt, daß bei Drehung der Trommel in Druckdrehrichtung beide Stopperelemente übereinander hinweggleiten und bei entgegengesetzter Trommeldrehung die Drehung der Scheibe blockieren. Hierdurch werden die Klemmelemente aus dem Schlitz herausgeführt. Bei Drehung der Trommel in Druckdrehrichtung werden dagegen die Scheiben, die mittels einer Zugfeder mit der Trommel verbunden sind, entgegen der Druckdrehrichtung bewegt, so daß dadurch die Klemmelemente wieder in den Schlitz hineingedrückt werden.

Abstract: For recording an analog signal by means of two recording heads (1A, 1B) equally spaced on a rotating drum (3), a magnetic tape (2) is wrapped around a guide drum (3) with an angular range of 90°, so that there are recording periods when a head (1A, 1B) is tracing the tape (2) and free periods when neither head (1 A, 1 B) is tracing the tape (2). The analog signal to be recorded is converted to pulse code modulated (PCM) signals having real time periods longer than the recording periods. The free periods, during which neither head (1 A, 1 B) is in contact with the recording medium (2), are used to add redundant data such as parity data and a cyclic redundancy check (CRC) code to the PCM signals. The composite signal, which represents a PCM signal having the parity data and CRC code added to it, is time-base compressed to a period substantially equal to the recording periods and is recorded on the recording medium (2) by one of the heads (1 A, 1 B) during its recording period. To reproduce the signal, the same head arrangement is used. The free periods are used for error correction and the error-corrected signal is time-base expanded to occupy the original or real time signal period and then reconverted into the corresponding analog signal.

Abstract: A method and an apparatus for producing a fasciated yarn, utilizing an air nozzle for false twisting a fiber bundle, provided with a fiber passage comprising an inlet portion, a small channel, and a large channel, characterized by the provision of at least a contact area in the inlet portion and/or the upstream region of the small channel. During the spinning operation, the fiber bundle is forced against the contact point, and, as a result, a twist imparted by a vortex can be effectively suppressed so that it does not ascend toward the upstream region. 
     Also, since ballooning can be suppressed by the contact point, the size of the small channel can be increased, resulting in the sufficient suction air in the inlet portion.

Abstract: A fluid dispersal device utilizes the Karman vortex street phenomenon to cyclically oscillate a fluid stream before issuing the stream in a desired flow pattern. A chamber has an inlet and outlet with an obstacle or island disposed therebetween to establish the vortex street. The vortex street causes the stream to be cyclically swept transversely of its flow direction in a manner largely determined by the size and shape of the obstacle relative to the inlet and outlet, the spacing between the obstacle and the outlet, the outlet area, and the Reynolds number of the stream. depending on these factors, the flow pattern of the stream issued from the outlet may be either: a swept jet, residing wholly in the plane of the device and which breaks up into droplets solely as a result of the cyclic sweeping, the resulting spray pattern forming a line when impinging on a target; or a swept sheet, the sheet being normal to the plane of the device and being swept in the plane of the device, the resulting pattern containing smaller droplets than the swept jet pattern and covering a two-dimensional area when impinging upon a target. A particular feature of the device is that it is moulded in one single piece from synthetic plastics material, the obstacle or island being an integral part of the single-piece moulding.

Abstract: O A tensed color selection electrode assembly is utilized in screening a pattern of phosphor areas upon the target surface of the faceplate of a color cathode ray tube and is thereafter incorporated as a component of the tube. The faceplate is formed of a material having a predetermined temperature coefficient of expansion and has registration affording means thereon. The initial assembly includes a severable mount formed of a material having a temperature coefficient of expansion greater than that of the faceplate and has a central opening of a predetermined expanse. A planar metal foil having a predetermined pattern of apertures and formed of a material having a temperature coefficient of expansion not greater than that of the mount is secured to the mount. First and second frames, each having an overall span less than the mount opening and each having a central aperture dimensioned to enclose the target surface, are formed of a material having a temperature coefficient of expansion approximating that of the faceplate. Each frame further includes a pair of spaced apart sealing lands with one sealing land of each frame disposed in a confronting relation. Devitrifying frit disposed between the confronting sealing lands bond the frames and a peripheral portion of the foil in sandwich fashion to maintain the foil in tension. Indexing means associated with the other sealing land of the first frame co-operate with the registration affording means on the faceplate to permit repeated precise registrations between the foil and the faceplate to facilitate screening of the phosphor pattern as well as to facilitate mating of the electrode assembly to the faceplate. Finally, the invention contemplates a method of utilizing the electrode assembly for screening a phosphor pattern as well as methods of making a color cathode ray tube having such an electrode assembly.
